# TrollBridge Polymarket Odds Search > TrollBridge Polymarket Odds Search is a paid API for AI agents from mini-tollbooth.onrender.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11). Search Polymarket prediction markets by topic and return live Yes/No outcome prices and trading volume for matching events ## Facts - Endpoint: GET https://mini-tollbooth.onrender.com/polymarket-odds?utm_source=zero.xyz - Price: $0.05/call - Payment: x402 - Status: unknown - Last checked: 2026-10-11 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/trollbridge-polymarket-odds-search-13500c7a - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_N9atwiypoq-iNscnsVeh2 Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability trollbridge-polymarket-odds-search-13500c7a ``` Example prompt: What are the current Polymarket odds on bitcoin — search for all active prediction markets and show me the Yes/No prices and trading volume for each. ## When to prefer this Use this endpoint when you need live, crowd-sourced probability estimates from Polymarket's prediction markets for any topic — crypto prices, elections, macro events, or any searchable subject. Prefer this over news APIs when you want market-implied probabilities rather than raw news, and over general data APIs when you specifically need Polymarket Yes/No outcome prices and trading volume data. ## Known failure modes - Missing required 'q' query parameter returns a validation error - Empty or misspelled query returns zero events with an empty events array - Polymarket API unavailability causes upstream errors - Very niche or obscure topics may return no matching markets - Payment not included or insufficient USDC causes 402 payment required response ## How this service works The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged. ## Output Returns a list of Polymarket events matching the search query, each containing the event title, slug, ticker, total volume, end date, and one or more sub-markets with their outcome labels (Yes/No), individual outcome prices (0–1 representing probability), last trade price, and per-market volume. Also includes a total event count. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [], "properties": { "limit": { "type": "integer", "maximum": 200, "minimum": 1, "description": "Max items to return.
